After getting the galaxy that appears at summer nights from Luna, Celestia wanted to do something for her birthday. When she got an idea, she spends her spare time experimenting weather magic, and when the time came in the winter, she ordered the weather patrol to arrange the clouds so she could enchant them. Once she did, the clouds gave a glow, similar to the star clusters of the night sky, and the snow that was falling looked like diamonds.“Diamond dust.” she officially called it.“And it will appear often in the middle of winter and will clear up at night. A gift for my dear sister, Luna.“Princess Celestia (c) Hasbro.Cutie Mark Vector (c) Parcly taxel
